I have a asp.net chech box control in the top of my page. I have a html table getting populated from DB on the page load. But, during the page load checkbox got rendered before the html table gets populated. So, the user is able to select the checkbox before the page completes the action and becomes unstable. My problem is, I couldn't disable and enable the checkbox after the page compltely loaded. As I tried this in the last line of Page_load event and also, using a Page_UnLoad event - no use. These events fired before I see the HTML table in my browser. Also, I tried in javascript (which is running after the html table populated), but there I could not enable the disabled check box.

I am making a small file hosting website, and each user can upload multiple files, and will have access to just his files and can't access others files, for example by guessing the URL.

View 3 RepliesI have a folder within my website called 'ProtectedPages' which contains pages which users can only see if they have logged in (MyAccount.aspx etc). If they bookmark that page and try to go to it without logging-in, they are immediately bounced to my login page.However, if I have text files, images etc. in there, then it seems users can get to these fine without the need to login - all they need is the URL. For example, I could send the URL http://mysite.com/ProtectedPages/MyAccount.aspx to a friend and he wouldn't be able to access it until he had logged in. However, I could send himttp://mysite.com/ProtectedPages/ATextDocument.txt and it would show it to him without any problems.How would I go about protecting ALL files within this folder? I have a web.config file within the ProtectedPages folder which just has this information in it (I don't want TrainingAdministrator's to have access to that folder at all)

I am using ASP.NET profiles with allowAnonymous="true". I am NOT using ASP.NET membership. I recently took a hard look at the aspnetdb database and noticed that although my site gets 600-800 unique visitors daily, there are 4000-5000 "users" being created in the database.
Clearly what is happening here is the users with cookies disabled end up creating a record for every request.
My question: How do I prevent user and profile database records from being created if the client doesn't support cookies or has them disabled?

I am implementing strightforward membership provider. I do not want new users to be able to login without being approved.
I have tried the setting on the registration wizard called DisableCreatedUser="True" and this does not work.
